Table 3.
Relationship between total fatigue score with sleep quality and its components in pregnant women referring to Tabriz health centers (n=605).
| Variables | Mean (SD)* | Md (P25%-P75%) ** | Correlation with total score of fatigue | |
|---|---|---|---|---|
| r | p | |||
| Total score of sleep quality | 6.56 (3.24) | 6 (9– 4) | 0.091 | 0.031† |
| Subjective sleep quality | 1.23 (0.89) | 1 (2-1) | 0.097 | 0.020‡ |
| Sleep latency | 1.51 (0.96) | 1 (2-1) | 0.063 | 0.134‡ |
| Sleep duration | 0.35 (0.74) | 0 (0-0) | 0.014 | 0.743‡ |
| Habitual sleep efficiency | 0.52 (0.75) | 0 (1-0) | -0.013 | 0.762‡ |
| Sleep disturbance | 1.49 (0.62) | 1 (2-1) | 0.098 | 0.019† |
| Use of sleeping medication | 0.20 (0.13) | 0 (0-0) | 0.004 | 0.917‡ |
| Daytime dysfunction | 1.46 (0.84) | 1 (2-1) | 0.116 | 0.005† |
| Total score of fatigue | 25.22 (7.26) | 24.9 (30.5-19.7) | -- | -- |
| Fatigue severity | 10.29 (4.69) | 10 (14-7) | -- | -- |
| Fatigue-induced distress | 4.85 (2.88) | 5 (7-2) | -- | -- |
| Fatigue interference in daily activities | 36.93 (19.42) | 34 (51-22) | -- | -- |
| Duration of fatigue | 4.63 (1.74) | 5 (6-4) | -- | -- |
The total score of sleep quality has a score ranging from zero to 21. The lower score shows the better situation of sleep. The total possible range of fatigue scores is 1 (no fatigue) to 50 (severe fatigue).
